Yes - this was me. Aside from the idle being ok (750) if the A/C is turned on, if I turned my streering wheel it would temporarily jump higher but then come back to down 500. But, as I mentioned in one of my previous posts, my rough idle issue has disappeared and I honestly have no idea why. Very odd...

Good luck to everyone. Hopefully someone will figure this out...
